Viruses are exceptions to the cell theory, but they have some characteristics of living things. What is one of these characteristics?
Option : (b)
All living organisms are linked to one another because
(a) they have the common genetic material of the same type
(b) they share common genetic material but to varying degrees
(c) all have a common cellular organization
(d) All of the above
Viruses lack cellular machinery and hence do not show any characteristics of life until they enter a living body/host and use the host cell to multiply.
Many transition metals form interstitial compounds. The characteristics of these interstitial compounds are:
I) they have high melting points
II) they are very hard
III) they retain metallic conductivity
IV) they are chemically more reactive than the pure metals.
